The guantlet has been thrown down between angels and demons...

In a land where the battle between Good and Evil is always near, the Black Knight's silver sword fells enemies with silent grace. The Black Knight has sworn the fallen angel, Lucifer de Morte will pay for the reign of terror wrought upon France, and upon the d'Ange family, where nearly all had died a terrible death. All but one...

Yet the Knight's hard-won battles and dented armor hides a larger secret—for 'he' is actually Seraphim d'Ange. She is traveling to de Morte's demesnes, executing his demon henchmen along the way. Now, aided by Baldwin, a family retainer, and Dominique San Juste, a mysterious stranger who knows far too much about the puissant powers of both heaven and hell, Sera grows closer and closer to her final target.

Little does she know that there is at least one more secret she herself holds.
